Also I think I read up about somebody that turbo'd theirs and it caused some damage...  ???
I can help you with that.  I told those boys not to go the rising rate regulator method cuz it'll bite ya...

Piggybacking a second set of injectors and another ECU to run them will cure those issues.  Not as cheap, but runs like a stocker until under boost when the second ECU kicks in.  The Busa boys have been piggybacking a MS unit for several years and that system is gaining serious respect in the turbo Busa world.  Just a thought.

ZG, if you remember my oil leak issue you will also remember that the ZX14 will not drop right in. The shaft drive and the drive are not interchangeable. >:(

Look at Bergmen's photos.

I'd be willing to lay odds that all you need to do is drill and tap a boss that is not used on the ZX, that is used on the ZG.

Mass manufacturing is all about saving costs by sharing the same thing across as many platforms as possible.

I thing the only actually different parts on a ZX14 longblock vs a ZG14 longblock are cams, pistons and final drive.  The head may be different only in the fact of accommodating the cam phasing hardware.  The difference in the 'cases' are probably which holes are drilled and tapped and which are not.

ZG,

The best way to find out is to get a ZX14 engine and set it side by side first.  Then you'd need to spilt cases and find out what makes the shaft bevel gear housing bolt up and make sure those bosses are on the ZX14 case.  If they are not there on an `06-`07, I'd lay odds they are there by the `08 MY when the C14 came out.

Electronics would be the least of my concerns now.  Cam phasing is all I would be concerned about, and I'd lay odds that Guhl can turn that function off in the ECU.  He's played with both the ZX and the ZG ECUs, so I'm sure he can locate cam phasing code in there.

I didn't think that cam phasing, which I think is what kawasaki refers to as the variable Valve Timing, was controlled by the ECU. I thought that it was a function of oil pressure. Or is it controlled by an ECU actuated valve and only uses oil pressure to do the work?

Cam timing is controlled through oil pressure by ECU.

I would imagine that a ZX14 ECU could be piggybacked for engine functions with some creative wiring.  However, if Guhl can emulate the various systems mapping and turn off undesired features of the ZG ECU, then that would be the easy and probably best thing.

AND even if the ZX14 cases cannot be converted to accept the ZG tranny/shaft, is it possible to put the ZX jugs and head on the ZG cases?  I know this has been discussed before, but IIRC the objections were lack of mounting bosses and the other things already being discussed in this thread.  Personally I see ZERO insurmountable problems IF getting the shaft on the ZX cases or getting the ZX aerobic systems mounted to the ZG cases can be accomplished.

Mounting different engines into various vehicles is basic hot rodding 101.  I've mounted Oldsmobile 215 V8 into a Vega as well as numerous small and big block Chevy engined Vegas.  Also two Corvairs, one an Olds 455 in the back seat (later converted to 454 Chev), another a Buick 350 in the front (yeah, in the Corvair's trunk).  I've put a 481 Chevy in a Geo Metro Wagon and a 350 into a Datsun Fairlady Z.  Every engine swap has problems to overcome.  Motorcycles can present (or at least SEEM to present more challenges than other vehicles (like boats, planes, or cars) but it all depends on what you want to accomplish and how badly you want to do it (it also may involve how much you have or do not have to spend on the project).

Personally I'd just turbo the thing, do it well, and enjoy.  That's the correct answer in my opinion.  If you DO get the ZX engine in there it's only gonna give you what... 50 hp tops?  I'd bet you'll want the turbo in six months anyway.  >:D

It's the old adage: "With enough money, anything is possible!". 'Tis true, but I always look at things in relation to time/effort/money vs. actual gains returned.
Yesterday I recommended just taking a ZG engine and have someone GOOD thoroughly massage it from the bottom-end up. Make a true fire-breather Jay! I think even staying naturally aspirated, 200hp would be a realistic and achievable goal. Use only top shelf components, go to a larger bore, bump compression, change cam profiles, caress and flow the head... do whatever can be done & build it right- You've already got the exhaust and sorting the fueling would be easy. There would also be no worries about wiring or having to mess with the final drive. Hell, you could probably even swap some of the transmission gear sets w/ ZX pieces if that would make for more optimal gearing.
Just thinking out loud here, and these are only what my desires would be if money were no object...

Do something similar to what SISF did, weld the Connie's tranny and shaft unit to the ZX motor! then simply install and have fun!!

I think the ZX ECU won't be needed.  I'd lay odds it's much simpler inside than the ZG ECU.  Plus you would integrate with the rest of the bike better, i.e. KiPass.

The ZG ECU runs a detuned, read lower CR, ZX engine with variably cam timing and KiPass.  I'm sure it could run a bone stock ZX engine out of the box.  My only concern is that if you eliminate the hardware that controls the variable cam timing, will that be important enough to cause the ECU to go into 'limp in' mode?  Or is it an ancillary system that the ECU could care less if it fails?

Personally, I'd throw stock ZX14 pistons into a ZG14 engine and not worry about anything else.

Maybe do a little port work and use the ZX throttlebodies and header size of course.

As for bolting it onto the frame, I would think it is a bolt in.  Remember the ZG frame is dimensionally the same as the ZX frame for the critical area, only with thicker casings to support the weight of touring.  The fuel tank is the same, the seats swap, the forks/fender/wheel are all the same.  How much truly changed?  Just the back half for the most part.

I actually did a lot of research on this once.... there are a few ways you could get it done with a first gen ZX14 motor. (Note: I have no idea about the ZX14R motor... I never looked into it much).

By far the easiest way to get it done would be to use the head, pistons, TB's, and exhaust from the ZX14 and graft them over; that would give you the same motor, sans the transmission aspects (note: the ZX14/C14 has no 'jugs', the cylinders and the block are a single piece.). The transmission ratios are much different, but would be fine left alone. The variable valve timing device could essentially be blocked off, and you'd need a sort of servo eliminator to keep the ECU happy... this is pretty simple if you have some knowledge on how electronics work (or a friend that does, hehe). Everything in the tranny is strong enough to deal with the ZX-14 parts. If you try to graft the lower case into the C14 frame it's a never ending nightmare of adapting the shaft drive and clutch components properly. Functionally (for HP, anyway), the ZX14 top end & pistons are the only difference. The head has a little less chamber volume and the pistons have less dish area. Combine that with the proper intake, exhaust, cam timing, and ECU trickery and it's a ZX14 again. :) You could accomplish the propper mapping with a reflashed ECU or the DJ piggback stuff, both are pretty simple but would require competent dyno tuning (hint: use the timing/fuel maps for a stock ZX14 in a reflashed ECU as a starting point and it'll be close...).

But a well put together turbo would be cheaper & faster, for sure.... and it would require a lot less work.  :) Rev Ryder had it right though: stay away from regulator-dependant, rising rate fuel systems. And cheap fuel pumps..... Nothing but tears.

I'm so sorry for your loss Spaz.  Fast as stink for a bit though.  You were really haulin' it.  Before yall went that route, I tried to tell Bruce about the rising rate regulator risk and the way they kill fuel pumps, but he felt David at Cycle Logic had a good handle on it.  They do work well as long as fuel pressure from the pump doesn't waver.  At least with a "smart" system, you can be warned of a problem and the ECU will do all it can to prevent meltdown including shutting you down to prevent it if programmed to do so.

It was pretty epic for 8K+ miles, and it will be again soon when I have the money for good parts. Truth be told, my 'professionally' modified fuel pump that I bought was actually a ZX-10R style pump with a stock Mitsubishi OEM pump installed and the internal bypasses and regulators epoxied over.... I think I'm still pretty pissed off about that. If the pump would have held out I would have been ok, but that's a big if that didn't pan out. I didn't know any better about the extreme rising rate stuff and the effects high pressures have on fuel pump flow (and wear!), but I sure do now. My supercharged ZX10R is using a genuine walboro with a 1:1 regulator and propper MAP sensor controlled fueling now.... 10psi on a stock motor and still kicking. :)

Back on topic:

I poured over factory part numbers and off the shelf parts when I had my motor apart. The C14 also has a different clutch set-up... the inner hub and pressure plate are quite different. The outer baskets can be interchanged, leading one to the conclusion that the crank & basket gears are the same. The gears and output shaft for the tranny are non-compatable. If you wanted the shaft drive to work on the zx14 you have to change that shaft, and then all the gears on it or the mating gears in the transmission... and then adapt the bevel gear housing on the zx14 case. Not worth it at all when you can just change the other parts on a concours motor to the ZX14 parts instead. That, and the C14 gearing is much more appropriate for a heavy bike that will be toured more often.

If you were willing to invest the R&D time into piston to valve clearances and such, you could probably even get the VVT to work on the C14 head with ZX14 pistons, and a little milling done to the C14 head to bring the chamber volume in-line the the ZX14.... but that's a LOT of work/testing there for sure. Just swapping to the zx14 head and eliminating the VVT gives you an easy, proven set-up that works.

In the end, the only thing that makes the ZX-14 more powerful than a C14 is increased compression, increased breathing ability (throttle bodies and velocity stacks), better exhaust flow, and the proper cam timing to link it all together..... and pushing it all through a slightly more effecient chain drive.

I agree on the preferred method would be to swap ZX14 pistons into the ZG14 block/case.

Biggest reason Bergmen went through the trouble he did is because the cylinder bore spacing on the ZRX1200 is more than the ZG1000/ZX11/ZRX1100.  So, to even use the stroke gained from the ZRX1200 crankshaft, he had to use the ZRX1200 cases.

Now he noticed similar things to what you speak about on the clutch and trans shafts from the ZRX to the ZG.  But he swapped in the complete ZG 6spd and it just dropped right in.  Therefore the trans output was setup to work with a bevel drive housing now, instead of the chain.

Now, if you wanted to swap in the ZX14R crank with it's longer stroke, that could cause issues in the stock ZG14 block/case.

Bergman mention in another thread a few weeks ago that the bevel gear housing from the C10 bolted right up to the ZRX cases with no modification. That had to be a sweet feeling when he realized that! >:D
Even if the transmission shafts swap directly between the ZX14 & the C14, I believe the problem is that the engine cases are different and don't allow for the bevel gear housing to be swapped as easily as they were on Bergman's bike.

I also think the case on the left hand side is different, but I am not 100% sure. Given the effort to replace the transmission and the gear ratios involved, though, it's just as easy and actually better to retain the C14 transmission and just do the piston/head nonsense. In the end, there's no uber-easy, bolt right up swap; you have to exchange some parts in one end of the engine or another.

I'd bet that a stroker crank could be made to fit, but now you're in new piston AND rod territory on top of final drive woes. Again, much easier and probably cheaper to bolt a charger up to it. :)
